Thank you it takes a lot of patience. Every app is very different. And often they lack in different features. For example you find one that allows you to create nice and smooth linework, only to see that you can't increase brush sizes over 20px which makes it pain to erase big areas fast. Another has got layer blending styles (multipy etc) but lacks in pressure sensitivity. So any time you pick an app to draw in, you have to compromise a bit. It's still tons of fun though and totally worth it
